Pulsar 4


Infrared Thermometry for Sulfur Reactors and High Temperature Furnaces

The E2T PulsarTM 4 Advanced measures two wavelengths for continuous and instantaneous measurement of refractory temperature (RT), gas temperature (GT) and integrated temperature (FF), reporting both readings simultaneously in one instrument. The E2T PulsarTM 4 is a single channel option for direct replacement of older Pulsar II models. The innovative Advanced Energy Smart FMA Flame Measurement Algorithm allows for accurate real-time flame transparency compensation and correction. Applying the flame transparency calculation with FMA removes the flame transparency errors due to the gas (flame) temperature, providing the highest accuracy in process temperatures.
